Short Step Syntheses of Indolo[2,3-a]carbazoles Carrying an Alkyl, Allyl, or a Glycosyl Group at the 11-Position and a Novel 6,7-Dihydro-13H-cyclopentano[mn]indolo[3,2-c]acridine Derivative
摘要:
Novel 1-alkyl-, 1-allyl-, and 1-beta-glycosyl-2,2'-biindolyls are prepared. Their Diels-Alder reaction produced 11-alkyl-, 11-allyl-, and 11-beta-glycosylindolo[2,3-a]carbazoles. Formation of a novel 6,7-dihydro-13H-cyclopentano[mn]indolo[3,2-c]acridine derivative is also reported.

Differentially substituted indolocarbazoles are readily prepared via a synthetic route employing two palladium catalyzedreactions. First, biindoles are prepared from a palladium catalyzed cross coupling reaction. Second, a new palladium catalyzed benzannulation reaction employing biindolyl iodides and alkynes provides indolocarbazoles.

The synthesis of indolocarbazoles was achieved via photochemical and thermal annulation reactions of chromium Fischercarbenecomplexes. This methodology allows for facile incorporation of hydrogen bonding functionality which complements the pharmacophore contained within bioactive indolocarbazole natural products.
